Do you know that the iPhone also has secret codes to carry out different things?
Every different smartphone has its secret codes derived from its manufacturer. Sometimes, it becomes difficult to track all secret codes and utilize them. This article will share some of the best cool iPhone secret codes.
20+ Best Hidden Codes
You must enter these secret codes into the dialer to find information about the device, masking calls, troubleshooting issues, etc. So, let’s check out some of the secret dialer codes for your iPhone.
Field Test Mode
If you are looking for a code that can provide you with technical details of your network, you need to use this code. This iPhone secret code can help you find the accurate signal strength of your network in decibels.
- First, make sure that your iPhone has an active cellular connection.
- Next, open the phone app and enter the code on the dialer
- On the Field test menu, tap on the LTE.
- On the next screen, tap on the Serving Cell Meas.
- Now, on the next screen, look at the numerical measurement behind rsrp0
The numbers behind the rsrp0 are your iPhone cellular signal strength in dBm.
For those unfamiliar, if the numbers behind rsrp0 are between -50dB to -60dB, the signal strength is excellent. The signal strength is good between -70dB to -90dB. Anything beyond -100dB means the signal strength is poor.
Enter Field Test Mode in iOS 10 or Earlier
If your iPhone runs on iOS 10 or earlier, you must follow a different method to enter the Field test mode. In iOS 10, you need to open your iPhone’s dialer, enter the code and tap the call button.
You will be redirected to the Field test page to find information about your network. If you wish to check the signal strength, hold the Power button unless the Slide to turn off option appears.
Once the Slide to turn off option appears, press & hold the home button instead of sliding. You will now see the network strength in decibels on your iPhone’s status bar.
Hide Your Caller ID
You might have received many calls on your iPhone with no or unknown caller ID; ever wondered how that is possible? Few carriers support hiding the caller ID, allowing users to make anonymous calls.
You can also hide your caller ID with the code we have shared, but the only criteria are that your carrier should support the feature. We have also shared the codes for different countries; type the code on the dialer followed by the number you want to call.
|Germany||*31# or #31#|
If your carrier supports hiding caller ID, your caller ID will be hidden or shown as ‘Unknown.’
Check the SMS Center
Whenever you send an SMS from your phone, it goes to the server or SMS center number. You can grab that SMS Center number with this code.
To check the SMS Center number on your iPhone, open the dialer, enter the code we have shared and press the call button.
Check the Call Waiting Status
You need to use this secret code if you doubt whether you have call waiting enabled or disabled on your iPhone.
Open iPhone’s dialer, type in the code, and press the Call button. You can see whether Call waiting is enabled or disabled on your iPhone.

Check Call Barring Status
If you wonder why you are not receiving any calls on your iPhone, you need to check the Call Barring Status. Call Barring is a feature that blocks both incoming and outgoing calls for those unfamiliar.
If the Call barring is enabled, your iPhone won’t receive any calls, no matter how good your network is. To check the Call barring status on your iPhone, open the dialer, type in the code we have shared, and tap on the Call button.

To disable the Call barring feature, enter #33*your SIM pin# and press the Call button.

If call forwarding is not enabled, the code will allow it to, and if it is enabled, this secret code will disable it.

Call Line Presentation is a service responsible for displaying the caller’s phone number when an incoming call arrives on your iPhone.
If Call Line Presentation is disabled, you will not see the phone number when someone calls you. You can confirm the same by using the code we have shared.
Show Your Mobile Number on the Caller ID
*82(number you are calling)
If your mobile number is hard blocked, you need to use this code in front of the number to show your number on the caller ID.
So, if your friends can’t see your number on their call screen, you need to use this code to show them your number or name.
Get the Local Traffic Information
